Abstract

Intrigued by the interesting Context Aware Crossover (CAX) operator proposed by Majeed and Ryan in a number of recent papers, this operator was tried on a real problem (solid catalysts optimisation) where unfortunately, no improvement was detected. An implementation of the benchmarks used in [MR06b] seems to show that the CAX is mostly an exploitation operator, boosting the average fitness of the population.
